I can only remember 1 vacuuming bug (which possibly could cause this) that *may not* be fixed in 4.10.x (depends on version and distro patches). This bug is: https://bugzilla.samba.org/show_bug.cgi?id=14147 I suggest that you check the source to see if the relevant patches have been applied. However, this bug is rare and you appear to be seeing it a lot. The previous links I provided summarise everything I know about this issue. I encourage you to read them carefully, see if you can find a bug, and hopefully contribute a patch. We have previously audited the code to attempt to find such bugs, concluded that out-of-memory was the only likely scenario, and then found appropriate messages in the logs to support this. You should probably take a similar approach. I would also suggest lots of careful testing as you upgrade. Good luck! peace & happiness, martin On Mon, 16 May 2022 23:18:11 +0800, hhhaaa hhhaaa via samba <samba at lists.samba.org> wrote:> thank you very much? > not "out of memory" > When there is a problem, I see that the memory does not report an error > > On Mon, May 16, 2022 at 6:26 PM Martin Schwenke <martin at meltin.net> wrote: > > > On Sat, 14 May 2022 20:38:36 +0800, hhhaaa hhhaaa via samba > > <samba at lists.samba.org> wrote: > > > > > I watched but couldn't solve the problem.we only have one client,it run > > > fastcopy business,and there are no performance issues. > > > https://wiki.samba.org/index.php/CTDB_Performance > > > > > > environment: > > > nodes:4 > > > ctdb:4.10.16 > > > os:centos7.6 > > > Crazy printing "high hopcount 1359100196 dbid:locking.tdb" every day . > > > > It is likely that you are running out of memory.
